Credit: ESO/L. Calçada With the help of ESO's Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close…

Discovery of iron-60 and manganese-53 substantiates supernova 2.5 million years agoCredit: Dominik Koll / TUM When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending…

Study shows destabilizing effect of the giant gas planetCredit: JAXA / ISAS / DARTS / Damia Bouic Venus might not be a sweltering, waterless hellscape today, if Jupiter hadn't altered its orbit around the sun, according to new UC…

A University of Colorado Boulder astrophysicist is searching the light coming from a distant, and extremely powerful celestial object, for what may be the most elusive substance in the universe: dark matter. In two recent studies,…

Credit: NAOJ A study of comet motions indicates that the Solar System has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from…

Scientists utilized citizen science network to observe the objectCredit: Southwest Research Institute SAN ANTONIO -- Sept. 28, 2020 -- A new study authored by Southwest Research In-stitute scientists Rodrigo Leiva and Marc Buie reveals the…

UC Riverside-led team's technique relied on determining the mass of galaxy clustersCredit: Mohamed Abdullah, UC Riverside. RIVERSIDE, Calif. -- A top goal in cosmology is to precisely measure the total amount of matter in the universe, a…

Credit: ALMA (ESO/NAOJ/NRAO), Tanaka et al. Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers spotted a pair of massive baby stars growing in salty cosmic soup. Each star is shrouded by a gaseous disk…

Survey of geosynchronous orbital debris led by University of Warwick found over 75% of debris detected could not be matched to known objects in public satellite catalogues Survey of geosynchronous orbital debris led by University of…

The temporal evolution of the universe, from the Big Bang to the present, is described by Einstein's field equations of general relativity. However, there are still a number of open questions about cosmological dynamics, whose origins lie…

Analysis of the event horizon telescope observations from 2009-2017 reveals turbulent evolution of the M87 black hole imageCredit: G. Wong, B. Prather, C. Gammie, M. Wielgus & the EHT Collaboration In 2019, the Event Horizon Telescope…

Scientists analyze sunquakes to pinpoint flare energy source, perhaps predict flare severityCredit: UC Berkeley graphic by Juan Camilo Buitrago-Casas Solar flares are violent explosions on the sun that fling out high-energy charged…

Spacecraft DAPPER will study "dark ages" of the universe in radio wavesCredit: NRAO/AUI/NSF, Sophia Dagnello The National Radio Astronomy Observatory (NRAO) has joined a new NASA space mission to the far side of the Moon to…

University of Warwick astronomers have shown that water vapour can potentially be detected in the atmospheres of exoplanets by peering literally over the tops of their impenetrable clouds. University of Warwick astronomers have shown…
